I'm wondering if those that have applied for medicine this cycle could help me out and let me know of any interviews you've had where you've been required to 1) sign a formal disclaimer, 2) been advised in an interview invite not to share interview information or 3) been advised verbally in the interview/before the interview. I'm trying to come up with a list for TSR and it'd help a lot.

I was required to sign for BL (I think, I can find out for you though), Leicester (definetely) and Keele (pretty sure I had to sign it in the pre-room wait before being called). Leciester also included that I was required to sign I had never attended a medical school before.

BL: I know I signed something for my BL interview... I'm just not sure what it was. I either didn't read it or forgot about it
Peninsula: I didn't get 1,2 or 3. In fact, after the first people were interviewed, the rest of us discussed it while we were waiting for ours (Provided the first person shared with us what was in the interview).
Imperial: Nothing. Some people were discussing it afterwards in the waiting room.

Manchester - we were told not to discuss it, but not formal disclaimer (people discussed it anyway, rather loudly as well :P)
Cambridge - they told us in a letter not to discuss stuff in the interview, but I don't think it was subject specific and nothing written
Imperial - nothing official nor were we told not to discuss
